Answer:

-3.662rad × 180/π = -209.8°

Step-by-step explanation:

Answer:

1 degree = .01745329 radians

1 radian = 57.2957877856 degrees

-209.8 degrees = .01745329 * -209.8 =

-3.66170024200 radians

Answer: 8 books (She will also keep with her a balance of $8)

Step-by-step explanation:

Total amount of money = $28

Cost of 4 books = $10

Sets of books able to be bought with the money = 28/10

                                                                                 = 2 (Reminder will be 8)

Amount of books able to be bought with the money = 2 × 4

                                                                                       = 8 books

Regina can purchase 11 books when she has $28 to spend.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

A bookstore is selling 4 books for $10 as part of its clearance sale. Regina has $28 to spend.

Let's represent the number of books Regina can purchase x.

The total price for x books at the clearance rate is 10/4x = $2.5x

Since Regina has 28 dollars to spend, she can purchase :

⇒ x = 28/2.5

Apply the division operation, and we get

⇒ x = 11.2 books.

Therefore, she can purchase 11 books.

Answer:

Company Y charges 255 dollars more then Company X :)

Step-by-step explanation:

Company X: 0.75 * 300 = 225 + 0 shipping

Company Y: 1.20 * 300 = 360 + 120 shipping = 480

480 - 225 = 255

Answer:

In the expression of 7xy, if x is negative, then y must also be negative for the product to be positive.

Answer:

Area = 35 cm^ 2

Step-by-step explanation:

Area = 1/2(a+b) x h

1/2 (5+9) x 5

= 35 cm^ 2

Answered by G a u t h m a t h

Answer:

A = 35  cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)

where h is the perpendicular height between the bases and b₁, b₂ are the bases.

Here h = 5 , b₁ = 9 and b₂ = 5 , then

A = [tex]\frac{1}{2}[/tex] × 5 × (9 + 5) = 2.5 × 14 = 35 cm²

Answer:

  y/x = -3/7

Step-by-step explanation:

Write the given relationship and solve for y/x.

  (x +y)/(x -y) = 2/5

  5(x +y) = 2(x -y) . . . . . multiply by 5(x-y)

  5x +5y = 2x -2y . . . . . eliminate parentheses

  7y = -3x . . . . . . . . . . . add 2y-5x

  y/x = -3/7 . . . . . . . . divide by 7x

Answer:

see explanation

Step-by-step explanation:

Using the sum to product identity

cosx + cosy = 2cos([tex]\frac{x+y}{2}[/tex] )cos( [tex]\frac{x-y}{2}[/tex] )

Consider left side

(cos5A +cos3A) + (cos15A + cos7A)

= 2cos([tex]\frac{5A+3A}{2}[/tex] )cos([tex]\frac{5A-3A}{2}[/tex] ) + 2cos( [tex]\frac{15A+7A}{2}[/tex]) cos( [tex]\frac{15A-7A}{2}[/tex] )

= 2cos([tex]\frac{8A}{2}[/tex]) cos([tex]\frac{2A}{2}[/tex]) + 2cos([tex]\frac{22A}{2}[/tex] )cos([tex]\frac{8A}{2}[/tex] )

= 2cos4AcosA + 2cos11A cos4A ← factor out 2cos4A from both terms

= 2cos4A( cos11A + cosA) ← repeat the process

= 2cos4A( 2cos([tex]\frac{11A+A}{2}[/tex] )cos([tex]\frac{11A-A}{2}[/tex] )

= 2cos4A(2cos([tex]\frac{12A}{2}[/tex])cos([tex]\frac{10A}{2}[/tex] )

= 2cos4A(2cos6A cos5A)

= 4cos4Acos5Acos6A

Answer:

Irrational

Step-by-step explanation:

If we evaluate the square root, we realize that the number will not be a perfect square.

Since it is not a perfect square, it will be an unending, never-repeating, decimal.

Therefore, it will be irrational.

Answer:

Always

Step-by-step explanation:

When two planes never intersect, they must always be parallel.

The answer can't be sometimes since planes can't sometimes intersect and be parallel.

The answer can't be never because two planes that are never parallel will intersect.

Therefore, two planes that do not intersect must always be parallel.

Answer:

Always parallel

Step-by-step explanation:

Parallel lines never intersect. Think of it like a never ending train track that goes only in a straight line. The two tracks will never cross each other!

=====================================================

Explanation:

The domain is the set of allowed x input values, aka the set of all allowed x coordinates of the points. We see that [tex]-4 < x \le 3[/tex]. It might help to draw vertical lines through the endpoints until you reach the x axis. Note the open hole at x = -4 to indicate we do not include this as part of the domain (hence the lack of "or equal to" for the first inequality sign).

The interval [tex]-4 < x \le 3[/tex] then can be condensed into the shorthand form (-4, 3] which is the domain in interval notation.

It says: x is between -4 and 3. It can't equal -4 but it can equal 3.

So the use of parenthesis versus square brackets tells the reader which endpoint is included or not.

--------------------------------------------------

The range describes all possible y outputs. We see that y = 5 is the largest it gets and y = -5 is the lower bound. It might help to draw horizontal lines through the endpoints until you reach the y axis. The open hole means -5 is not part of the range.

The range as a compound inequality is [tex]-5 < y \le 5[/tex]. This condenses into the shorthand of (-5, 5] which is the range in interval notation.

Verbally, the range is the set of y values such that y is between -5 and 5. It can't equal -5 but it can equal 5.

Answer:

Step-by-step explanation:

Answer:

Sin 73 = 0.956304756, Cos 17 = 0.956304756

Sin 18 = 0.3090169944, Cos 72 = 0.3090169944

This only works when the Sin angle and the Cos angle are complementary, meaning they add up to 90 degrees.

55+35=90

30+60=90

15+75=90

73+17=90

18+72=90

(Keep in mind the values for the Sin and Cos are approximations)
